Effect of sowing date on flowering and seed set of mustard (Brassica juncea L.)
Manju Devi and Harish Kumar Sharma
The present study was conducted to determine the effect of sowing date on flowering and seed set of mustard (Brassica juncea L.). The studies were conducted in the mustard crop by inducing the plant to flower early or late through different sowing dates. The crop was sown during October- November in three different dates at an interval of fifteen days. Delay in sowing caused a significant reduction in the length of flowering period. The crop sown on D1 had the longest flowering duration (45 days) followed by the crop sown on D2 (41 days) and D3 (35 days). In the present investigations, crop sown on D1 took significantly more days from sowing to the flowering stage as compared to D2 and D3. Delayed sowing of mustard resulted into reduction in the seed set due to short flowering duration. Delaying sowing time resulted in significant reduction in the seed set. Seed set percentage, 1000 seed weight and seed siliqua-1 did not vary significantly among different dates of sowing.
